BACKGROUND OF THE DISCLOSURE 1. Field of the Disclosure

The disclosure relates in general to self-intermittent urinary catheters, and more particularly, to a self-intermittent urinary catheter extension with infection detection. It will be understood that the system of the present disclosure is not limited to self-intermittent catheters, but can be utilized in association with, among other structures, indwelling catheter systems, without limitation.

2. Background Art

The urinary tract consists of the kidneys, bladder, ureters, and urethra. Urine in the bladder is normally sterile. This means it does not contain any bacteria or other germs (such as fungi). But bacteria can enter the urinary tract through the urethra. This can cause a urinary tract infection (UTI). A UTI can happen anywhere in your urinary tract, including your bladder, ureters, kidneys, and urethra. Most UTIs are easy to cure with antibiotics. But an untreated infection can become more severe as it spreads toward the kidneys. An infection in the upper urinary tract is much more challenging to treat. Eventually, the infection can spread into your blood, causing sepsis and frequently, death.

Individuals with spinal cord injuries or other maladies that preclude them from sensation in their lower body have Neurogenic bladders, which necessitates them to void their bladder 5 to 7 times a day through use of a self-intermittent urinary catheter. Because of limited sensation, UTIs are not sensed right away and therefore, treatment is late. There is an extremely high incidence of UTIs and subsequent complications in this population due to these issues, frequently resulting in complications, other medical issues, hospital stays, and often—sepsis and death.

DETAILED DESCRIPTION OF THE DISCLOSURE

While this disclosure is susceptible of embodiment in many different forms, there is shown in the drawings and described herein in detail a specific embodiment(s) with the understanding that the present disclosure is to be considered as an exemplification and is not intended to be limited to the embodiment(s) illustrated.

It will be understood that like or analogous elements and/or components, referred to herein, may be identified throughout the drawings by like reference characters. In addition, it will be understood that the drawings are merely schematic representations of the invention, and some of the components may have been distorted from actual scale for purposes of pictorial clarity.

Referring now to the drawings and in particular to FIGS. 1 and 2, the self-intermittent urinary catheter extension assembly (herein referred to as “extension assembly”) is shown generally at 10. As will be explained below, the extension assembly is configured for coupling to a self-intermittent urinary catheter. The extension assembly is not limited to use therewith, but can also be used with other types of catheters, and can also be used in closed systems, such as, for example indwelling catheters and Foley catheters, among others. For illustrative purposes only, and not for limiting purposes, the extension assembly will be described in the environment of a self-intermittent urinary catheter with the understanding that it is not so limited in use.

The extension assembly 10 is shown as comprising extension tube 12, extension connector 14, indicator assembly 16 and bag coupling connector 18. The extension tube 12 is shown as comprising a tubular member formed from a polymer, such as a latex free polymer. In many configurations, the tubular member may be clear and transparent, while in other configurations, the tubular member may be translucent or opaque and in varying colors. The extension tube 12 extends between proximal end 20 and distal end 22. The extension tube defines an outer surface 26 and an inner bore 24, which, in the configuration shown, defines a substantially uniform cylindrical configuration with a substantially uniform wall thickness. Of course, variations are contemplated in the configuration and cross-sectional shape of the extension tube.

The extension connector 14 comprises body 30 and cover member 78. The body 30 preferably comprises an injection molded rigid polymer component that is integrally formed and monolithic. Of course, multiple component constructions are likewise contemplated, wherein the multiple components can be co-molded, or separately molded and attached together mechanically through mechanical coupling, adhesive coupling and/or welding or the like. The body 30 extends from first end 32 to second end 34 and central bore 36. In the configuration shown, the central bore is substantially circular in cross-sectional configuration while variations are contemplated.

The body 30 further defines a tube coupling assembly 40, a catheter coupling assembly 50 and a central test portion 56. In the configuration shown, the tube coupling assembly is configured to be attachable to the extension tube. The tube coupling assembly includes outer surface 42 and proximal stop 44. In one configuration, the proximal stop defines a flange, such as flange 46 which provides a positive stop as the extension tube is extended over the outer surface of the tube coupling assembly. The outer surface 42, in the configuration shown defines a plurality of barbs which are configured to sealingly engage the inner bore 24 of the extension tube in engagement. It will be understood that the relative sizes are such that the extension tube is both sealed against the outer surface of the tube coupling assembly and that it is also resistant to separation. In such a configuration, the extension tube is stretched over the barbs of the outer surface.

In another configuration, the outer surface may be substantially smooth and the extension tube may be slid over through stretching (wherein reliance is made on the inward biasing of the extension tube) or through an adhesive. In some configurations, such as the configuration shown in FIGS. 8 and 9, a cavity 48 may be created at the inner end of the tube coupling assembly which can be defined by an outer rim 47 that is concentric with and spaced apart from the outer surface 42 of the tube coupling assembly 40. It will be understood that various combinations of outer surfaces and various couplings (mechanical through stretching, adhesive or the like) can be combined with each other to create variations on the different structures disclosed herein.

The catheter coupling assembly 50 is shown in FIG. 3 through 5 as comprising outer surface 52 and proximal stop 54. In the configuration shown, the proximal stop comprises a ridge 55 representing the proximal end of the catheter coupling assembly. The outer surface 52 comprises a barbed configuration of slightly increasing diameter. Such a configuration allows for the sealed engagement with a variety of catheters in a sealed arrangement. In other configurations, a fewer or greater amount of barbs as well as greater dimensional changes are contemplated. Furthermore, it is contemplated that in still other configurations, the outer surface may comprise a smooth surface, or a different configured surface for engagement in a sealed manner with the catheter (or another tubular member). With reference to FIG. 3A, the central bore 36 thereof may include inwardly directed ribs 43 that extend along the central bore generally along the length thereof at least partially between a first and second end thereof. These ribs 43 increase the turbulence of the fluid within the central bore and provide improved contact between the fluid (urine) and the radial passage (so that the fluid can improve contact with the indicator assembly). In the configuration shown, a plurality of ribs 43 (in the configuration shown, three ribs spaced at 120° from each other) extend longitudinally along the central bore between the radial passage and the first end of the extension connector.

As to the central test portion, a plurality of central test portions 56 may be positioned radially separated from each other about the central portion 57 of the body 30. In the configuration shown, two central test portions are positioned 180° apart from each other, or, on opposite sides of each other. In other configurations, a single central test portion may be utilized. In still other configurations, more than two central test portions may be disposed along the central portion of the body. It will be understood that in the configuration shown, the pair of central test portions are substantially identical to each other, while, in other configurations, the different test portions may have different configurations (which may be due to positioning, due to different testing structures positioned therein, among other variations). As such, one of the central test portions will be described with the understanding that the other test portion may be substantially the same in configuration.

The central test portion 56, in the configuration depicted, comprises slot 58 and radial passage 59. The slot 58 is defined by lower end wall 60 and upstand walls 62 which collectively define cavity 63 and upper opening 70. In the configuration shown, the slot comprises a substantially rectangular slot having a substantially planar and rectangular lower end wall 60, a catheter side wall 64, an extension side wall 66, a first joining wall 68 and a second joining wall 69. The joining walls are generally perpendicular to the lower end wall 60. The width and length of the resulting slot are dimensionally larger than the height thereof.

While a rectangular configuration is shown, the slot is not limited to such a configuration. For example, the slot may comprise a cylindrical configuration, with the lower end wall being substantially circular. Other polygonal configurations are contemplated, such as triangular or hexagonal lower end walls. Furthermore, it is contemplated that the base surface may be arcuate so as to be concentric with the inner bore 24 of the extension connector 14. Additionally, it is contemplated that the upstanding joining walls may comprise walls that are perpendicular to the arcuate lower end wall, or, where the lower end wall is planar, the upstanding joining walls may be oblique thereto. Furthermore, it is contemplated that each wall may be disposed at a different angle relative to the lower end wall. It is likewise contemplated that the upstanding walls may be other than substantially planar.

The radial passage 59 is shown in FIGS. 4 and 5 as comprising a passage that includes inner end 72 and outer end 74. The radial passage places the cavity 63 in fluid communication with the central bore 36 of the extension connector. In the configuration shown, the radial passage may comprise a bore that extends through the lower end wall. Such an opening is dimensionally smaller than either the width or the length of the lower end wall. Such an opening may be centrally located, or may be offset to any one of the walls (typically, toward one of the catheter side wall 65 or the extension side wall 66, FIGS. 10 and 11). In the configuration shown, the bore comprises a cylindrical configuration, while other configurations are contemplated.

In another configuration, as is shown in FIGS. 12 and 13, the radial passage may comprise a slot, that for example, extends between the first joining wall and the second joining wall proximate the catheter side wall, for example. In other configurations, the slot may be spaced apart from the catheter side wall or the extension side wall or adjacent either one (or both). In other configurations, such a slot may be positioned in alternate directions, such as for example, between the catheter side wall and the extension side wall, and along one of the first and second joining walls.

A cover member 78 (FIG. 4) may span across a portion of the central test portion 56 that is on opposing sides of the slot 58 so as to provide a substantially (if not fully) fluid tight cover over the upper opening 70 of the central test portion. It is contemplated that at least a portion of the cover member will include a transparent portion so as to provide visual access to the slot for purposes of observing the indicator assembly. In the configuration shown, the cover member comprises a hoop-like structure having a catheter side seal 77 and an extension side seal 79 that seals against opposing surfaces that matingly engage with the same. In other configurations, the cover member may be coupled to the central test portion through an adhesive in place or in addition to a mechanical coupling.

With additional reference to FIGS. 6, 7, 14 and 15, the indicator assembly 16 includes an indicator 80, a wicking member 90 and a liner 87. In the configurations shown, the indicator includes a top surface 82, a bottom surface 84 opposite the top surface 82 and edges 86 which define the shape of the indicator assembly. As will be understood, the indicator comprises a woven or non-woven material (such as an absorbent pad or the like) which includes a chemical that has a color reaction to a particular substance. That is, the presence of the substance triggers a color change providing a visual confirmation of the presence of the substance. The particular substance that is monitored can be varied, with the understanding that, for purposes of the present disclosure, the substance to be monitored provides an indication of a bladder infection. In the configuration contemplated, the indicator comprises a material that is available from Teco Diagnostics of Anaheim, Calif. Other materials are contemplated for use therewith.

The wicking member includes an upper surface 92, a lower surface 94, an indicator contact portion 96 and a flow contact portion 98. The upper and lower surfaces generally are planar and define a wicking member, in the present configuration, that is substantially uniform in thickness, and substantially flexible. An edge defines the outer perimeter of the wicking member. The wicking member essentially provides for the delivery of fluid at a controlled rate or a controlled flow or volume from the flow of urine to the indicator 80. In various configurations, a portion of the wicking member is in fluid communication with the flow of urine through the central bore, and that portion comprises the flow contact portion 98. Additionally, a portion of the wicking member is in fluid communication with a surface and/or an edge of the indicator thereby defining the indicator contact portion 96. In the configurations shown, the wicking material is in physical contact with the indicator. In the configuration shown, the wicking member comprises a material likewise available from Teco Diagnostics of Anaheim, Calif.

In some configurations, the wicking member remains within the slot, entirely. In other configurations, the wicking member is positionable within the slot, with a portion of the wicking member extending into the radial passage (FIGS. 12, 13, and the indicator assembly of FIG. 14). For example, the wicking member may extend into the radial passage where, again, for example, and not to be deemed limiting, the radial passage comprises a slot extending from the first joining wall to the second joining wall along one or both of the catheter side wall and/or the extension side wall. It will be understood that, in other configurations as well, the wicking member may extend into the radial passage, and may be shaped so as to extend into the radial passage in a particular configuration and/or orientation.

The liner 87 includes an upper surface 88 and a lower surface 89 the upper and lower surfaces cooperate to define an outer perimeter. The liner is preferably utilized to preclude and/or limit the exposure and/or movement of fluid either to or from the indicator. In some configurations, the liner overlies a portion of or an entirety of a surface (such as the bottom surface) of the indicator when the indicator is positioned within the slot. In at least some configurations, the liner is sandwiched between the bottom surface of the indicator and the lower end wall 60 of the slot 58. In some configurations, the liner may be continuous or may include openings. In one such configuration of FIGS. 1 through 5, the liner is sandwiched between the lower surface of the wicking member and the lower end wall of the slot of the central test portion. In such a configuration, the liner includes an opening so as to allow direct contact of fluid from within the central bore to communicate with the wicking member.

In the configurations shown, the indicator generally has a square configuration that matches the shape of the slot 58. In other configurations, it will be understood that the shape of the slot may be varied, and according, the shape of the indicator. In other configurations, it will be understood that the shapes may not match, or may match. It will further be understood that in some configurations, the edges of each of the indicator, the wicking member and the liner may be identical, whereas in other configurations, the wicking member may extend along various surfaces and may extend as an appendage from the indicator and/or the liner. Various combinations of the same are contemplated.

It is also contemplated that the indicator assembly may extend fully around the entirety of the extension connector, and, may be positioned in the central test portion, or may be positioned elsewhere. For example, in some configurations, a slot may be provided in the tube coupling assembly as opposed to the central test portion, and an edge thereof may be exposed to the stream.

The bag coupling connector is shown in FIGS. 1 and 2 as comprising outer end 100, inner end 102, outer surface face 104 and central bore 106. The bag coupling connector can be extended over the distal end of the extension and may be coupled to a bag. In other configurations, the extension may be directed to a toilet, a urinal, or to a collection container and may be loosely associated with the same, in place of being coupled thereto by way of the bag coupling connector or the like.

In operation, as the catheter is utilized, there is flow of urine through the inner bore of the extension assembly, and then the central bore of the extension connector. The flow of urine through the central bore of the extension connector eventually directs at least some portion of urine through one of the radial passages 59 in the central test portion. As the urine passes through the radial passage, the urine contacts the wicking member 90. The wicking member 90 through wicking action pulls the urine into the wicking member and directs the urine from the flow contact portion toward and into the indicator contact portion of the wicking member. Continued wicking eventually has urine reach the indicator. As the urine interacts with the indicator, if certain chemicals are present, then the indicator will experience a color change indicative of the presence of the chemical. The presence of the chemical is an indication that there is a high probability of a bladder infection. On the other hand, if there is no color change, there is indication that the bladder is free of infection.

By transferring the urine from the flow to the indicator through the wicking member, the amount of urine that reaches the indicator can be minimized. Such minimization precludes the inadvertent removal of the underlying test chemicals within the indicator and generally preclude the bleeding out of the chemical from the indicator. Additionally, the liner 87 further precludes the bleeding out of the chemical from the indicator, leaving sufficient chemicals to allow for the indicator to effectively point out, or, identify, the presence or absence of an infection.

It will be understood that the same principles that are in the extension connector can be applied to a catheter itself. That is, the body of the catheter can have the structural features of the central test portion of the body and the indicator assembly. One such configuration is shown in FIG. 16. In such a configuration, the catheter assembly 310 includes catheter tube 301, and connector 314. The central test portion 356, and in particular the slot 358 and the radial passage 359 thereof (in addition to the cover) can be adapted to the body of the catheter. The structure of the central test portion 356 may be similar to, or identical to the central test portion of the extension connector (FIGS. 1 through 14), as can the indicator assembly 16.

As with the extension tube, the catheter tube 312 is similar to an extension tube, having a distal end 322 that allows for insertion into the body. As will be understood, the distal end is shaped so as to extend into the body, and includes openings that are placed in fluid communication with the urine in the bladder of a user.

The catheter tube 312 can be coupled to the body 330 in place of the catheter coupling assembly of the extension connector. The opposing end can be coupled to an extension 303 or the like, directly, or through other structures known to one of skill in the art.
